CUSH|ONED HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 591,252, dated October5, 1897.

Application filed June 17, 1897.

To ail whom it may concern.-

Be it known that I, JOHN B. GRAVIS, a citizen of the United States, anda resident of Canton, county of Stark, State of Ohio, have invented anew and useful Improvement in Horseshoes, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, making part of this specification.

My invention relates to improvements in horscshoes; and it consists ofcertain features of construction and combination of parts by which asoft-rubber cushion is held in engagement with the horseshoe by means ofa clamping-plate, and the same may be readily removed, when desired, forthe purpose of renewing the rubber cushion, as will be hereinafter morefully described and claimed.

Figure 1 is a perspective view of the clamping-plate. Fig. 2 is aperspective view of the rubber cushion. Fig. 3 is a perspective view ofthe shoe. Fig. 4 is a plan view of the shoe. Fig. 5 is a detailperspective view showing one of the methods of engaging theclampingplate to the shoe at the heel thereof. Fig. 6 is a sectionalview through the toe or front of the shoe and showing the relativepositions of the several parts.

In the accompanying drawings similar letters of reference refer tosimilar parts.

A represents a horseshoe having. formed upon its outer edge clips a,terminating in raised portions a at the heel and at right anglesthereto. In the base of the shoe are provided the usual perforations afor the passage of the nails, and in the center of the forward portionthereof, adjacent to the toe,there is provided an L-shaped slot (1Adjacent to the heel and on the righthand side of the shoe there isprovided a perforation a for the purpose of engaging the projectingprong upon the retaining or looking plate, and upon the other oropposite side of the shoe there is provided a loop or staple a for alike purpose. Either form may be used, or one may be used, as shown, onone side of the shoe and the other upon the other. Through the raised orclosed portion of the heel there are provided upon either side twoperforations a and a for the purpose of engaging the projecting prongsof the retaining-clamp and the stiffening-wire Serial No. 641,108. (Nomodel.)

passing cushion.

B represents a soft-rubber cushion adapted to conform to the shape ofthe inner portion of the shoe A and having a projecting toe b, whichrests upon the metal toe of the shoe A, and an inwardly-projectingflange b, which is adapted to rest upon the bottom of the shoe. Passingentirely through the soft-rubher cushion B and extending from each heelthereof there is a stiffening-wire b the projecting ends of which areadapted to engage with or pass through the holes a in the heel of theshoe. Upon either heel of the rubber cushion there is countersunk aslotbiadapted to receive corresponding prongs or proj ections upon theclamping or retaining plate.

0 is a light metal clamping or retaining plate adapted to conform insize and shape to the configuration of the inner portion of thesoft-rubber cushion B and having formed upon its inner flanged portionand upon either heel thereof projecting lugs or tongues c 0', adapted toengage with the shoe A, and a lug or tongue 0 adapted to engage with theslot 5 in the rubber cushion B. In the forward or toe portionof thelocking-plate 0 there is provided a hole 0 through which there is passedthe retaining-bolt D. The retaining- 8o bolt D is slipped into the L-shaped slot at in the shoe A. The rubber cushion is then placed in.position and a loop or hooked wire (1 engages the stifiening-wire 19which passes through the rubber cushion B. One end of the hooked wire dis then passed around the clamping or looking bolt. Plate 0 is placed inposition and a retaining-nut cl is screwed upon the bolt, thus holdingall parts in engagement.

In operation theshoe or base-plate A is first fitted to and nailed tothe foot of the horse. The rubber cushion B is then placed in position,the extending ends of the stiffening-wire b engaging with the openingsof in the heel of the shoe. The retaining or looking plate 0 is thenplaced in position, the respective prongs c, c, and 0 thereof engagingwith the shoe and the rubber cushion. The

through and around the rubber bolt D is then placed in position and theWire I00 d engages the stifiening-wire b therewith. The nut d is thenplaced in position and se curely screwed down, holding and clamping thecushion B in position. In case it should be desired to remove thecushion B for any purpose of renewal or otherwise the nut is removed.The clamping or looking plate is then readily withdrawn and the rubbercushion is in position to be removed or adjusted, as may be desired.

I am aware that heretofore there have been metallic shoes adapted to benailed to the foot of a horse and having clips-or flanges andsoft-rubber portions to engage therewith held in engagement with theshoe by means of screws; but such a construction has proved to beimpractical because of the fact that the screws became disengaged by thecontinued use of the shoe; but my device overcomes all thesedifficulties, and, while providing a soft cushioned shoe having ametallic base or plate for engagement with the hoof, at the same timeprovides an easy means for renewing the rubber cushion and a safe meansof holding it in position while in use.

Having thus fully described my invention,

what I desire to secure and claim by Letters Patent is- 1. A11elastic-tread horseshoe comprising a metallic plate, having formed uponits outer edge clips terminating in vertical flanges at the heel, arubber cushion seated therein, a clam pin g-plate having projecting lugsengaging the metallic plate, and a retaining-bolt,

substantially as described and for the purpose set forth.

2. An elastic-tread horseshoe comprising a metallic plate having formedupon its outer edge clips terminating. at the heel in vertical flangesat right angles thereto, a rubber cushion seated therein and carrying astiffeningwire, the free ends of which engage the vertical projectionsat the heel, a clampingplate having projecting lugs adapted to engagethe metallic plate, and a retaining-bolt by means of 'which the metallicplate and clampingplate are held in engagement, substantially asdescribed and for the purpose set forth.

3. The combination in an elastic tread horseshoe, of a metallic platehaving formed upon its outer edge clips, closed heels at right anglesthereto, a rubber cushion adapted to be seated therein, and aclamping-plate conforming thereto and having projecting flanges adaptedto engage with the metallic plate, and a retaining-bolt by means ofwhich the metallic plate and clamping-plate are held in engagement,substantially as described and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 14th day of June,A. D. 1897.

JOHN B. GRAVIS.
